Hello guys
Hoping you can shed some light on this. Every now and then (no set pattern) the attached message pops up from Avast. I have looked in the folder, unhidden system files etc but cannot find the setup.exe Avast is showing.
I have run some other programs (Malwarebytes etc) but it doesn’t detect anything.
Any suggestions would be very much appreciated.
Steve
I will clean the temporary files with CCleaner.
If you put the mouse over the file name (in the window) you’ll see the full path, wouldn’t you? Still then, does the file does not exist?
Which window?
The one you’ve posted before (screenshot).
Sorry, misunderstood.
I have since turned off a uLead Video editor I installed and that now seems to have cured it. I don’t think it was a virus, just Avast being careful.
Thanks for your posts.
Ok. Come back whenever you want or need help 
Thats very kind of you, thank you
